Technical drawing → verified workshop cutting list · Prototype v0.1 · Accuracy over speed — nothing is silently invented
connecting…
Welcome 👋
Upload a technical drawing (left) or load the sample test drawing. The system will:
Read dimensions deterministically from the PDF text layer (OCR fallback for scans where available) — every value traced to its location on the drawing.
Reconstruct components with visible formulas. Assumed sections are labelled INFERRED, never hidden.
Flag missing sizes, joint allowances and low-confidence items as blockers.
Let you correct, approve and export a workshop-ready cutting list.
⚠ Prototype honesty note: image-only/scanned drawings and freehand dimension lines need manual verification. The app will tell you exactly what it could and could not read.
Blue boxes = text the extractor read (dimension-bearing blocks). Click a component on the right → its evidence dimensions highlight red. Click a box → see its parsed value below.

Totals (deterministic)
Edit any cell. Editing a value sets its source to MANUAL. Set Status = VERIFIED only after checking against the drawing. Unticking “Joint allowance TBC” means you have confirmed the cut length includes machining allowances.

🔴 Blockers must be fixed in the cutting list or explicitly accepted below (recorded in the export). 🟠 Warnings don't block approval. Approving marks this saved version production-ready — any later edit resets approval.
Approbateur = utilisateur connecté (journalisé)
Chaque résultat important est recalculé par une seconde méthode indépendante et comparé automatiquement. Un ÉCHEC bloque l'approbation et ne peut pas être « accepté » — il faut corriger la cause. Les avertissements demandent une vérification humaine.
PDF includes a “✓ cut” tick column, totals (pieces, net m³, linear metres by section) and signature lines. Draft PDFs carry a red NOT-APPROVED banner; unverified rows are shaded.
Excel adds the formula/traceability column and a Flags sheet — keep it as the audit record.
Future module (brief §6, not in v1): stock-length optimisation with kerf + cutting diagrams, built on these same totals.
